inclusive.

It is well known that dyes having S OzY or -SO CH=CH group are useful as reactive dyes for dyeing fibrous materials. The present inventors have found that the present dyes having the Formula I mentioned above have superior fastness, colour brightness and fixa tion. It is the present inventors who first found these characteristics of the present dyes.

The object of the present invention is to provide novel reactive dyes which are useful for dyeing fibrous materials. Another object of the present invention is to provide a process for producing the above-mentioned novel reactive dyes. Further the object of the present invention is to provide a process for dyeing fibrous materials with the above-mentioned dyes. Furthermore the object of the present invention is to provide novel reactive compounds and a process for production thereof. And other objects of the present invention will be made clear by the following text.

The fibrous materials in the present invention include cellulosic materials such as cotton, linen, viscose rayon and staple fibers of regenerated cellulose, nitrogen-containing fibers such as wool and polyamides and polyvinyl alcohol fibers.

The dyes of the present invention are novel and the present dye residues are of azo dyes, metal-containing azo dyes, anthraquinone dyes, phthalocyanine dyes, diphenylamine dyes, oxazine dyes, formazyl dyes or Xanthene dyes, among which water-soluble azo dyes, metal-containing azo dyes, anthraquinone dyes and phthalocyanine dyes are especially preferable.

The present dyes are prepared by (a) reacting dye residue mentioned above and having one or more active hydrogens with a compound represented by the formula,

-NHCONHCH2OH SOzZ wherein X and X are the same as defined above and Z is the same as Y or -CH CH OH group, in an appropriate ratio, in sulfuric acid, or

(b) reacting a dye residue mentioned above and having one or more active hydrogens with a compound represented by the formula,

NH O O NH:

s OzZ (III wherein X X and Z are the same as defined above, together with Formalin, paraformaldehyde or dichlorodimethyl ether in sulfuric acid. In both cases the reaction is conducted in -100% sulfuric acid or in low concentration fuming sulfuric acid for several hours. One to five mole of the compound (H) or (III) is, preferably, employed per one mol. of the dye residue. When concentrated sulfuric acid is used in the above reaction, the compound (I) where Y is --CH CH OS0 H is directly obtained from the compound (II) or (III) where Z is -CH CH OH. Compound (I) where Y is --CH=CH is obtained by further treating the compound (I) where Y is wherein M is hydrogen, ammonium, alkali metal or alkaline earth metal and m is 1 or /2, or -CH CH Cl with acid-binding agents. In such dye synthesis, active hydrogen atom in the dye residues is removed due to dehydration or dehydrochlorination, and then methylene group is bound directly to the aryl nucleus or substituted for the end amino group, as in the Formula I. The active hydrogen of the dye residues is on phenyl nucleus which constitutes a portion of dye structure, particularly, on such nucleus having alkyl, alkoxy or phenoxy group; or on sulfonarnide, carbamide, aminotriazynyl or urea group. When the dye residues are particularly of azo dyes, the introduction of such reactive groups can be effected in the intermediate stage.

In this case, the adducts can be derived to the present dyes by such a manner as, for example, diazotizing, coupling, metallisation and condensation.

The compounds represented by the Formulae [II and III are novel compounds. The compounds represented by Formula III are prepared, for example, by reacting compounds represented by the formula,

S OzZ (1V wherein X X and Z are the same as defined above, with potassium or sodium cyanate or urea in a high yield according to the method described in Organic Synthesis, vol. 31, page 8 (1951), and further the compounds represented by the Formula II are prepared in a high yield by a conventional atmospheric hydroxymethylation of the compounds (M1), for example, by reacting the compounds (III) with formaldehyde in a neutral or weakly alkaline aqueous solution at 3040 C.

The typical examples of the compounds represented by Formula II or III are shown in the following Table 1. In the Table 1, kinds and positions of the substituents SO Z, X and X are shown on the assumption that the urea group or methylolated urea group is substituted at 1 position of the benzene nucleus.

Various dyeing processes may be applied, in wide range, such as a conventional dip dyeing, printing, padding etc.

Dip dyeing of cellulosic textile fiber is operated by adding an inorganic salt such as sodium chloride, sodium sulfate, etc. into a dyebath in the presence of an acidbinding agent such as sodium hydrogen carbonate, sodium carbonate, sodium hydroxide, sodium phosphate, etc., at relatively low temperature.

In padding method the material to be dyed is padded in an aqueous solution containing the dye. At the same time of or after the application, steaming or heat-treating is effected at relatively high temperaturesuch as 70l80 C., in the presence of an acid-binding agent such as sodium hydrogen carbonate, sodium carbonate, sodium hydroxide, sodium phosphate, sodium silicate, etc. Alternatively, fibers having been padded by a solution containing the dyestuff only may be treated at relatively high temperature, such as 80l00 C., in a bath containing the acidbinding agents.

Further alternatively, boiling-treatment in a water bath containing a great quantity of inorganic salt may be effective instead of steaming or heat-treating. In case sodium silicate is used as an acid-binding agent, it is not always necessary to conduct the treatment at such a high temperature as above mentioned, and satisfactory dyeing is obtained even at a relatively low temperature such as 20- 70 C.

Printing process can be operated by printing, onto fiber, a paste which can be obtained by adding dye and the above-mentioned acid-binding agent to thickening agent such as alkyl-cellulose, sodium alginate etc., and if necessary, followed by steaming or heat-treatment at 70l C., or by printing with printing paste without containing an acid-binding agent and treating the printed fiber in a bath containing the above-mentioned acid-binding agent, or by printing a printing paste without containing an acidbinding agent, and printing a .paste containing an acid binding agent onto the printed fiber and then, if necessary, followed by steaming or heat-treatment. In this manner, it is also possible to resist dyeing by using an acid.

The dyeing of nitrogen-containing fiber can be operated in a neutral to weakly acidic dyeing bath by a conventional method, and in this case, more preferably a nitrogen-containing nonionic surface active agent or cationic surface active agent may be added as a dyeing agent, and after dyeing the dyeing bath may be subjected to neutralization with a weak alkali such as hexamethylentetramine.

After dyeing, it is preferable to remove dyes, which are not bound to fiber, with soaping treatment or washing with water. Dyed materials thus obtained have remarkably excellent various fastness.

The dyes represented by the Formula I are novel and, in practice, the dye residues are of all kinds of dyes and even a non-colored compound may be employed as a dye residue, and in this case, it is possible to color a fiber in such a manner as diaZo-coupling after dyeing on the fiber.

Preferred dyes of the present invention which are of the phthalocyanine type may be represented by the following formula,

(50 m x1 Pc (3) (SOZNHR) n 2 (3) (ACH2NHCONH wherein P0 is a copper or nickel phthalocyanine nucleus; X and X each represent hydrogen, methyl or methoxy; M is hydrogen, an alkali metal or an alkaline earth metal; Y is CH CH OSO M or CH=CH and the SO Y group is bonded with the phenyl group at a 3 or 4 -position to the ureido group; R is hydrogen or EXAMPLE 1 (E113 IYUICOGII;
